I'll go first. Babymetal is coming out with a brand new album, Metal Resistance, on April 1st. In the meantime, they also released their first music video from the album, titled "Karate". I know it's a weird mix of J-Pop/Idol music and Heavy Metal, but it's just too good to not recommend. Aside from the musical genius of producer Kobametal, their dance choreographer, Mikikometal, is also a friggin' genius.

If you're skeptical of the mix of metal and kawaii-ness, play the video and immediately close your eyes. Just listen to the music first. Seriously. Once you get past the weirdness, it's great. The awesome choreography and performances by the girls just put it on another level of greatness, but the music itself stands alone, solid.
